GAS-ENGINE.

SPECIFICATION forming part'of Letters Patent No. 616,974, dated January 3, 1899.

Application filed December 4, 1897. Serial No. 660,825. (No model.)

To aZZ 1071 0172, it may concern.-

Be it known that I, CARL C. RIOTTE, a citizen of the United States, residing at New York city, New York county, State of New York, have invented certain new and useful Improvements in Gas-Engines, of which the following is afull, clear, and exact description.

My invention relates to improvements in gas-engines; and it consists particularly in improving the means whereby the oil and air are mixed in suitable proportions to form the desired explosive gas or vapor.

The object of my invention is to provide a simple, inexpensive, and effective means whereby suitable proportions of air and oil may be mixed to form the explosive mixture.

Referring to the drawings, Figure l is a plan view of my invention, the pipe leading to the engine being removed. Fig. 2 is a section on the line 2 2, Fig. 1.

A is a hollow casing. B is a pipe leading therefrom to the exploding-chamber in the cylinder of the engine. (Not shown.)

D is awall within the casing A. This wall I) has a preferably circular opening at the top thereof, forming an air-passage.

E is an air-supply pipe leading into. the space formed by the wall D within the chamber A. F is a tubular guide centrally located within said space determined by the wall D.

G is an oil-supply pipe connected tov the casing A below the guide F.

H is a passage in the casingAthrough which the oil is conducted to the tubular vaporizer I. This vaporizer I may be of any desired construction and may be provided with any number or style of jets I at its upper end. These jets I should be directed by preference into the pipe 13, as shown.

J is a valve by which the flow ofoil through the passage H and into the tube I of the vaporizer is regulated.

K is a valve moving in the tubular guide G. This valve K is. by preference hollow, so as to be light in weight and sensitive in action. This valve K cuts off the flow of oil from the supply-pipe G to the passage Hand vaporizer I and is intermittent in its action. At the upper end of said valve K is adamper L, preferably circular in form and of approximately the size of the circular opening or airpassage at the upper edge of the wall D. M is a stem connected to said valve K and damper L and projecting up through the top of the casing A and provided at its upper end with a handle M.

N is a light spring inside the casing and around the stern M and exerting a gentle downward pressure to the valve K. The lower end of the valve K and its seat should be by preference ground in oil, so as to make a perfectly tight joint.

0 0 are outlets in the lower part of the casing A, through which any useless accumulation of oil may drip.

It should be understood that I purpose to use any of the well-known means for igniting the explosive mixture, said igniter being located in or near the cylinder of the engine, and therefore not shown.

Operation: The valve J is first opened. The valve K, is then opened by elevating by hand until oil has assumed its level in the vaporizing-tube. The fly-wheel of the engine should then be turned to create a vacuum to draw air into the mixing-chamber in the direction of the arrows indicated in Fig. 2, or, if desired, a suitable pump may be provided to force the air in this direction; As the air rushes past the vaporizer it draws out a small quantity of gasolene (or other suitable oil) in minute drops, which mixes with the air and forms the initial charge. As soon as this reaches the igniter it explodes and gives an impulse to the piston. The next stroke of the piston creates the vacuum, which draws in air through the pipe E, lifting the damper I and momentarily opening the valve K to permit more oil to flow into the vaporizertube. The influx of air rushing past the vaporizer draws out another charge of oil, which mixes with the air, as before. It will be observed that the vaporized oil is drawn into the mixing-chamber from out of the vaporizer at every other stroke of the piston. lVhen the piston recedes on one of these alternate strokes, a vacuum is created and air is drawn in, which draws some of the oil out of the vaporizer, and this mixed air and oil is drawn into the exploding-chamber of the engine.

011 the return stroke of the piston this is compressed and then exploded in the usual manner. As a consequence of this explosion the piston recedes, but airis not then drawn in through the damper, but said damper remains closed, because the back pressure resulting from this explosion keeps the damper, and consequently the valve K, closed, so that no air or oil is drawn out at that time. After the first charge has been ignited and the engine set in motion the handle M is released and the valve K intermittently opens and shuts as the air is sucked in past the damper L at each alternate stroke of the piston.

Regulation: Should it be found that the oil is being fed in too large quantities to form an explosive mixture of the correct proportions, the supply of oil may be cut down by means of the valve J, which may be a needlevalvecor a valve of any other suitable form. It will also be observed that in normal action the air in the pipe E is at the ordinary atm ospheric pressure and is supplied in substantially uniform quantities. Hence the mixture is regulated entirely by the valve J.

Vhat I claim is 1. In combination a vaporizing-chamber having an air-entrance passage, a vapor-exit passage, an atomizing-nozzle Whose tip is located away from said air-entrance passage and substantially in said exit-passage, a fluid connection to said nozzle, and valve mechanism controlling the passage of air past said nozzle and also said fluid connection, and allowing fiuid to pass to said nozzle only as air is drawn out of said exit-passage, said valve mechanism being operated to open the same by the flow of air through one of said passages.

2. In combination a vaporizing-chamber having an air-entrance passage, a vapor-exit passage, an atomizing-nozzle Whose tip is located away from said air-entrance passage and substantially in said exit-passage, afluid connection to said nozzle, and valves joined together so as to operate substantially at the same time controlling the passage of air past said nozzle and also said fluid connection, and allowing fluid to pass to said nozzle only as air is drawn out of said exit-passage, said valves being operatedto open the same by the flow of air through one of said passages.

Signed at New York this 24th day of November, 1897.
